Answer: time=4 hours
Explanation:
formula:
speed = [tex]\frac{distance}{time}[/tex]
time = [tex]\frac{distance}{speed}[/tex]
time= x
speed = 120km/hr
distance = 480 km
x = [tex]\frac{480 km}{120km/hr\\}[/tex]
=[tex]\frac{48km*hr}{12km}[/tex]
cut the zeros
and remove the signs
then
[tex]\frac{48}{12}[/tex] = 4
therefore, time taken to deliver the shipment by trucker is 4 hours
